Application filed December 22, 1916. Serial No. 138,393.

l'o all whom t 'may concern.'

Be it known that I, Osxn KLinN, n subject et the King of Hungary, and a resident of the city of New York, borough of Manhattau, in the county and State of New York, have invented n new and Improved lernumation-Lock, of which the following is a full, clear, und exact description.

This invention relates to locks of the permutation type and has ii'or its general objects to improve and simplify the construction and operation oi devices of this character so as to be reliable and eiiicient in use, conn paralively simple :ind inexpensive to nianufacture, and so designed that the combination con be easily and quickly changed whenever occasion requires.

A more specific ol "ect of the invention is the provision of a lock of that type including' a` barrel rotatably mounted in a Stationary casing, there being novel means within the barrel for operatively connecting theV barrel with the latch or bolt, whereby the latter is thrown outwardly or Withdrawn by the cani action between the bolt and the edges ot the bolt opening inthe barrel as the latter is rotated.l

A further object 'of the invention is the provision ot' a novel arrangement of tuinblers and baille plete with means whereby the barrel oif the lock can be operated so as to act :is a bolt-throwing means by the pressing of nvbuttonwhen thetumblers are in the desired position. l

With such objects in view, and others which will appear ns the description proceeds, the invention comprises various novel 'features oi construction und arrangement of parts which will be set forth with particuarity in 'the following description and claims appended hereto.

Referring to the drawing, l designates a door or equivalent body, and 2- the door jamb, which latter has n latch plaie into which the latch or bolt 4 is adapted to engage to lock the door l in closed position. The permutation lock A is mounted in a socket 5 in the door end the holt is thrown into and out oi locking` position throiurh n. slot (i in the door. l

rlhe lock A. comprises o stationery casing:r 7 suitably fastened in the door, and within the casing" is rotatably mounted the barrel 8, which has one end projecting out from theputer face ol' the door sons to 'torni a riln which can bc `gripped for turning.;- the rotatable part of thc loch', said i'nojccting port beingl circular and bearing' an alpha,-v hetical index t), whereby the desired permutations can be obtained. The front end of the barrel has a circular opt-.ningr l0 'from' which project the lumblers il, whereby the latter can he nnluipulatcd, and also projecting` out of the open end oi the barrel u pushbutton 12 for enabling the barrel to be operatively connected with the bolt for throwing` or `witlulrawing the saine. "lhe openr or :face end of the barrel is closed by n disk or face plate 13 which is provided with posts 14 that are fastened by vscrews 15 to an inner plate 1G. the hitter in turn ,being fastened by screws 17 to an internal whereby the tumblers can be engaged by the an annular space 1 9 ybetween the periphery of the plate 13 and the internal surface of the barrel, such annular space serving to The tumaccommodate the tumblers 11. blers, of which there are ourin the' present instance, have external lugs 2O which are engageable by the fingers to adjust the tuniblers to the desired position, and the inner ends of the tumblers have laterally extending lugs 21 which coperate with a baliie plate or disk 22 to control. the-operation of the lock. The tumblers are tree to be moved laterally in the annular space 19 when the y baiiie plate 13 is in -its normal position. The outer extremities 20. form knobs or grips fingers for moving them. Each tumbler has within its body a vspring-pressed follower 28 which, by engaging in any one of a series of recesses 24 on the inner surface of the.

index-carrying flange '9,insures the holding of the tumblers in position to Vwhich they are adjusted. The inner ends of the tumblers engage an annular internal shoulder 25 on the barrelf The baiile disk 22 is provided in its periphery witha series of reo 'cesses 26, and all of these recesses,v except fsa four, are closed by adjustable baiiiing devices in the form .of screws 27, four slots being left .vacant so as to coperate with theA four tumblers to enable the desired combination for operating the lock 4to beobtained.

vThis baiiie disk' will preferably have the recesses lettered to correspond with the alphabetical index 9 on the front of the barrel.

.When the. tuinblers areadjusted ,so that they register fwith their respective .open

slots 26 in theA baiiiedisk,-uthe latter can be shifted from the position shownin Fig. '3) t that Ashown in Fig. 5, which is the position the-bailedisk occupiesv when thetbolt is being thrown to and from locking position by the turnin of the barrel 8. This shifting of the ba e plate is performed b the pushbutton 12,`whi ch engagesthe ba e plate or disk 22 at the point 29. Behind the battle plateare helical' compressionv springs 30, which yieldingly hold the baiiie plate forwardly against the face plate, as shown fin Fig.'3. The springs 30 are kept in place vby the retaining plate 16. j

The'bolt'fi has its end 31. pivoted at 32 tol a suitably fired part, such as the inner arm. 34 of a bracketl 35`. which is fastened as shown in. Fig i to the fixed casing 7 of the lock. The bolt? passes through a slot 36, the

financessitedirection the bolt is withdrawn. ,The barrel is turned, through one hundred and eighty degrees to project or withdraw the bolt and the casing of the lock has a slot 39 slightly greater than hundred and eighty degrees to accommodate the Ainotion. of the bolt. to its arm 3d 'a .forwardly projecting central shaft. e0 which is stationary and carries at its forward end oppositely extending lugs 41 which engage ina diaxnetricalj recess 42 in the baiiie plate 22, whereby nor- 'The bracket 35 has fastened,

mally the latter'is pre-vented from. turning,

but when the pushbutton is, 'pressed rinwardly from the position shown in Fig. 3 to that shown in Fig. 5, the lugs 41 dovnot lie within the recess 42,' so that `the bao plate and barrel turn as a unit, it being understood that the posts 14 pass through lapertures 14' in the baiiie plate, so-that the latter can move the tumbler. To4 hold the barrel in the easing the bracket 35 may be provided with a lng 43,-Figsf3 and 13, which engages under an internal annular flange llemon the inner end of the'barrel. To permit access to the lock the casing may have`l a removable plate v4:5 at its inner end.

From the foregoing description taken in connection with the' accompanying drawings,th'e advantages ofthe construction and;

method of operation vwill be readily under' stood by lthose skilled in the art to which the invention appertains, and While I have described the principle of operation, `together with 'the device which now oonsider 'to be lthe best embodiment Jthereof,

desire to have it understood that the device shown is rnerely illustrative aiijd that such changes may be made when desired as fall Within the scope o ig' the appended claims.

l-laving thus described my' invention, I claim as new and desire tc `sedurre by Let ters Patent: 1'. A l`lock comprising a stationary casing having a slot, a barrel within'the casing and having a slot', a single bolt-'mounted Within the barrel on a fixed pivotal lcenter' and 'havingf'its'end normally disposed in the slot and' adapted" to be engaged by opposite edges, of the slot in the barrel for projecting or-retracting the bolt by the relative turning of the casingand barrel, means normally prevent-ing the relative turning of 'anisrn for unlocking the barrel from the easing 4for permitting relative` rotation.

2. A 'permutation lock comprising a casing,.a barrel rotatably mounted therein, said casing and barrel haying registering slots,
